Abstract
Objective: To observe the feelings of listening to music and the importance of music in the daily life of post-lingual deaf adults with cochlear implants, and to explore the relevant influencing factors. Methods: This was a cross-sectional survey study. From January 2021 to August 2021,the Music-Related Quality of Life Scale was used to evaluate the music needs and music experiences of 63 post-lingual deaf adults who met the inclusion criteria, including 27 males and 36 females, aged (40.7±12.3) years, at the time of surgery (36.8±13.1) years, and with a preoperative hearing aid ineffective time of (3.9±5.8) years. Indicators analyzed included age, duration of ineffective preoperative hearing aid wear, preoperative music preference, duration of postoperative cochlear implant use, current hearing aid modality, and auditory rehabilitation outcomes. Whether the six factors mentioned above constituted an influence on the subjects' music listening was investigated using SPSS 25.0 statistical software. Results: All of the observations in the scale were correlated with a single factor. The two sub-dimensions of music experience section were related to the effect of auditory rehabilitation. In the importance section, the effect of auditory rehabilitation was the influential factor of the dimension of "participation importance", and the preoperative enjoyment of music was the relevant influential factor of the dimension of "perceived importance". There was a significant difference between the groups when they were grouped by the above factors (P value<0.05), while there was no statistically significance between the groups when they were grouped by other factors (P value>0.05). Conclusions: Post-lingual deaf adults show the need and attempt to listen to music after cochlear implantation. The effectiveness of auditory rehabilitation and the degree of music preference preoperatively are two important factors that influence music listening in implant recipients. Once the level of auditory communication has been restored to a certain degree, it is important to pay more attention to the needs of music for implant recipients and train them in time, especially for those with music preferences preoperatively.

Abstract
BACKGROUND This Escherichia coli-produced bivalent HPV 16 and 18 vaccine was well tolerated and effective against HPV 16 and 18 associated high-grade genital lesions and persistent infection in interim analysis of this phase 3 trial. We now report data on long-term efficacy and safety after 66 months of follow-up. METHODS This phase 3, double-blind, randomised, controlled trial was done in five study sites in China. Eligible participants were women aged 18-45 years, with intact cervix and 1-4 lifetime sexual partners. Women who were pregnant or breastfeeding, had chronic disease or immunodeficiency, or had HPV vaccination history were excluded. Women were stratified by age (18-26 and 27-45 years) and randomly (1:1) allocated by software (block randomisation with 12 codes to a block) to receive three doses of the E coli-produced HPV 16 and 18 vaccine or hepatitis E vaccine (control) and followed-up for 66 months. The primary outcomes were high-grade genital lesions and persistent infection (longer than 6 months) associated with HPV 16 or 18 in the per-protocol susceptible population. This trial was registered with ClinicalTrials.gov, NCT01735006. FINDINGS Between Nov 22, 2012, and April 1, 2013, 8827 women were assessed for eligibility. 1455 women were excluded, and 7372 women were enrolled and randomly assigned to receive the HPV vaccine (n=3689) or control (n=3683). Vaccine efficacy was 100·0% (95% CI 67·2-100·0) against high-grade genital lesions (0 [0%] of 3310 participants in the vaccine group and 13 [0·4%] of 3302 participants in the control group) and 97·3% (89·9-99·7) against persistent infection (2 [0·1%] of 3262 participants in the vaccine group and 73 [2·2%] of 3271 participants in the control group) in the per-protocol population. Serious adverse events occurred at a similar rate between vaccine (267 [7·2%] of 3691 participants) and control groups (290 [7·9%] of 3681); none were considered related to vaccination. INTERPRETATION The E coli-produced HPV 16 and 18 vaccine was well tolerated and highly efficacious against HPV 16 and 18 associated high-grade genital lesions and persistent infection and would supplement the global HPV vaccine availability and accessibility for cervical cancer prevention.

Abstract
Objective: To explore the safety and efficacy of tumor-infiltrating lymphocytes (TILs) extracted from tumor tissue in patients with pulmonary metastasis of osteosarcoma, the TILs were amplified in vitro to reach clinical dosage and reinfused to the patients combined with high-dose interleukin 2 (IL-2). Methods: Twelve subjects with pathologically diagnosed osteosarcoma were enrolled from December 2019 to June 20, 2021 in Shanghai General Hospital. All subjects progressed with metastasis after standard chemotherapy and failed multiple lines of treatments. Fresh tumor tissue was obtained from the metastatic site and extracted and amplified by Good Manufacturing Practice (GMP) workshop to produce TILs to clinical treatment dosage (109-1011). High-dose IL-2 (100 000-200 000 U/kg) was administered immediately after autogenous TILs infusion to promote the activation, proliferation and antitumor cytolytic activity in vivo. Adverse events (AE) were graded according to Common Terminology Criteria for Adverse Events (CTCAE) standard and tumor response was assessed according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Results: One patient did not receive treatment due to failure in isolating TILs, total of 11 patients received a single re-infusion of autologous TILs. There were 10 males and 1 female with a median age of 19.9 years (12-33 years). Six of these patients received higher dose levels of 1.0×1010 TILs. The 11 patients were followed-up for 1 to 13 months and tolerated well. The most common adverse events reported were fever (10/11), constipation (3/11) and elevated gamma-glutamyl transferase (GGT) (3/11). The high incidence of fever was due to the IL-2 infusion. All patients experienced a transient drop in lymphocyte count and leukopenia leading to non-myeloid ablative lymphocyte clearance. The AE included grade 4 hematologic toxicity, including 8 cases of lymphocytopenia, 2 cases of neutropenia and 1 case of thrombocytopenia. No AE of neurotoxicity occurred. Of all the 11 patients, 9 patients got stable disease (SD) and 2 patients had progressive disease (PD). The disease control rate was 9/11. The median duration of SD was more than 4 months, and the maximum tumor volume decreased by close to 20%. Patient number 9 had sustained SD status for more than 6 months. Conclusions: TILs with in vitro expansion ability could be isolated from tumor tissues of advanced osteosarcoma patients. TILs amplified and reinfused in vitro have anti-osteosarcoma activity.

Abstract
Objective: To investigate whether pre-lingual deafness adult caused by inadequate auditory compensation in childhood can benefit from cochlear implants and the related influencing factors. Methods: A total of 26 prelingual deafness as experimental group [11 males and 15 females, the age of operation was (24.5±5.7) years] and 13 postlingual deafness as control group [5 males and 8 females, the age at the time of operation was (42.2±11.4) years] were recruited. Objective assessment included hearing threshold and speech recognition rate tests while wearing cochlear implants. Subjective assessment used Nijmegen Cochlear Implant Questionnaire to assess hearing-related quality of life of subjects. The changes of hearing ability in the prelingual deafness group before and after operation and the differences with the postlingual deafness group were compared, and the correlation between speech recognition ability and the age diagnosed as severe or profound deafness, the age of hearing aid invalid, and duration of wearing cochlear implant were analyzed as factor indicators. All statistical results were analyzed by SAS 9.4 software. Results: In terms of objective indicators, the speech recognition rate of pre-lingual deafness was significantly lower than that of post-lingual deafness [(35.4±28.0)% vs (80.9±8.0)%,t=7.67, P<0.001], while there was no statistical difference in hearing threshold between the two groups [(34.8±4.0) dB HL vs (33.1±3.7) dB HL, t=1.30, P>0.05]. The indicators in the subjective questionnaire showed that the prelingual deafness group was only weaker in advanced sound perception, confidence and total mean score than the post-lingual deafness group (P<0.05), and there was no significant difference in other aspects(P>0.05), meanwhile, all indicators of the prelingual deafness group were significantly improved compared with the preoperative level (P<0.001). There was a moderate positive correlation between the hearing quality and the speech recognition rate in the prelingual deafness group(r=0.51, P=0.008). The regression analysis showed that the invalid age of hearing aid was the exact influencing factor of speech recognition rate. Conclusions: Certain prelingual deaf adults can adapt to cochlear implants and obtain different degrees of auditory assistance. Compared with the improvement of objective auditory ability assessment, the patient who received cochlear implantation gain more improvement in auditory related quality of life subjectively. The ineffective age of preoperative hearing aid is an important factor, which needs to be aroused sufficient preoperative attention.

Abstract
Objective: To evaluate the effects of a high-protein diet on anthropometric indices and blood lipid in overweight and obese children and provide evidence for their dietary management. Methods: This was a Meta-analysis. The randomized controlled trials on the effects of a high-protein diet on anthropometric indices and blood lipid in overweight and obese children published up to January 19, 2022 were searched in PubMed, Web of Science, Embase, Cochrane Library and CNKI database, with the key words of "child" "adolescent" "obesity" "overweight" "pediatric obesity" "weight loss" "dietary protein" "dietary carbohydrate" "caloric restrict" both in English and Chinese. The quality of the included literature was evaluated according to the "risk of bias" assessment tool, which included bias from the randomization process, deviation from intended interventions, missing outcome data, measurement of the outcome and selection of the reported results. Moreover, calculated the pooled mean difference, perform heterogeneity test, and assess publication bias. Results: A total of 8 articles were selected from the retrieved 4 836 articles, all in English. The sample sizes ranged from 4 to 120. The analysis showed that the post-intervention body mass index (mean difference (MD)=-0.66, 95%CI -1.76-0.44), body mass index Z-scores (MD=-0.09, 95%CI-0.23-0.05), fat content percentage (MD=-1.07, 95%CI-2.88-0.74), high density lipoprotein (MD=0.02, 95%CI-0.02-0.06) and low density lipoprotein (MD=0.04, 95%CI-0.08-0.17) were not significantly different with those of the standard protein diet group, with P values being 0.240, 0.220, 0.250, 0.360 and 0.480, respectively. Subgroup analysis showed that after excluding one study, the difference in body mass index between the short-term intervention group and control group was statistically significant (MD=-1.60, 95%CI-3.14--0.06, P=0.040). Conclusions: A short-term high-protein diet intervention seems to improve the body mass index status of overweight and obese children. Nevertheless, a high-protein diet does not affect any other selected anthropometric indices and blood lipids. More studies with large sample sizes, higher quality and comparable standard of high-protein diet are needed for further demonstration.

Abstract
Pollution caused by fine dust is becoming a global problem in the aquatic environment. Many studies have investigated the hazards that fine dust may pose to terrestrial organisms; however, information on the effects on aquatic environments remain limited. In this study, the physicochemical characteristics of the fine dust associated with the captured powder or liquid state were compared using scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDS). Raw fine dust (RFD), in the captured powder state, was suspended in water (SFD), and the elemental composition, morphology, and size distribution of both were analyzed. Zebrafish were used as a model to study the effects of SFD-exposure on aquatic organisms. A fatal malformation was observed in the integuments of zebrafish exposed to SFD, specifically in the exterior and interior eye tissues. Furthermore, the exposure of SFD to Tg (flk; EGFP) zebrafish remarkably increased ocular vessel diameter expansion along with blood flow velocity. Regarding vessel diameter expansion, EA.hy926 cells exposed to SFD were adversely affected, with a significant increase in cell migration and capillary-like structure formation, which are angiogenic markers. The SFD-induced angiogenesis in vitro and in vivo was dramatically restored to normal via α/β-adenosine isolated from the anti-angiogenic brown algae Ishige okamurae extract. Taken together, the current study presents solid evidence of the altered physicochemical characteristics of SFD compared to RFD, and the detrimental impact of SFD in an aquatic in vivo zebrafish model. In addition, the protective effect of α/β-adenosine, a marine natural product, on SFD-induced angiogenesis suggests that it can be used as an agent to reduce the adverse effects of SFD on aquatic animals.

Abstract
Sargassum fusiformis is among the most important edible brown seaweeds in Eastern Asia that contains various bioactive compounds and strong activities. Saringosterol acetate (SA) was successfully isolated from S. fusiformis in our previous research. In this study, SA was investigated for its anticancer effect on MCF-7 breast cancer cells. SA attenuated the survival rate of MCF-7 cells with an IC50 value of 63.16±3.6 μg/mL. Staining with Hoechst 33342 demonstrated that SA treatment mediated apoptotic body generation. SA significantly downregulated Bcl-xL and upregulated Bax, and cleaved PARP, and cleaved caspase 3 in a dose-dependent manner. Thus, these results suggest that SA induced mitochondria-mediated apoptosis in MCF-7 cells, making it a plausible candidate for drug development against breast cancer.

Abstract
Objective: To investigate the effects of temperature-sensitive hydroxybutyl chitosan hydrogel on wound healing of full-thickness skin defect in rats. Methods: The experimental research method was used. Fifty-one no matter male or female Sprague-Dawley rats aged 7-10 weeks were selected, and two round full-thickness skin defect wounds with a diameter of 2 cm were created on the back of each rat at a distance about 1.0 cm to the spine. The rats were divided into temperature-sensitive hydrogel group, gel group, and blank control group according to the random number table, with 17 rats and 34 wounds in each group. Wounds of rats in the first two groups were applied respectively with 0.3 mL temperature-sensitive hydroxybutyl chitosan hydrogel and carboxymethyl chitosan hydrogel immediately after injury, and the wounds of rats in blank control group received no treatment. The wounds of rats in the three groups were all covered with vaseline oil gauze. The states of temperature-sensitive hydroxybutyl chitosan hydrogel in wounds of rats in temperature-sensitive hydrogel group and carboxymethyl chitosan hydrogel in wounds of rats in gel group were observed every day when the dressings were changed, and the difficulty of vaseline oil gauze removal was recorded. On the 3rd, 7th, 10th, 14th, and 21st day after injury, the wound healing of rats in the three groups was observed and the wound healing rates were calculated. On the 3rd, 7th, 10th, 14th, and 21st day after injury, tissue from 4 wounds of 2 rats in each group was collected for the following observation and detection. The infiltration of inflammatory cells, angiogenesis, and re-epithelialization were observed by hematoxylin eosin staining. The regeneration and remodeling of collagen fibers were observed by Masson staining, and the collagen volume fraction was calculated. The expressions of interleukin-6 (IL-6), transforming growth factor β1 (TGF-β1), and matrix metalloproteinase-1 (MMP-1) were detected by enzyme-linked immunosorbent assay method. Data were statistically analyzed with analysis of variance for factorial design, one-way analysis of variance, and Bonferroni test. Results: The carboxymethyl chitosan gel in wounds of rats in gel group was liquid gel and could flow with the body position, while the temperature-sensitive hydroxybutyl chitosan hydrogel in wounds of rats in temperature-sensitive hydrogel group was solid gel and could not flow with the body position, and the distribution of the latter was more uniform. The vaseline oil gauzes were easily removed in wounds of rats in temperature-sensitive hydrogel group, while the vaseline oil gauzes were difficult to remove in the other two groups. On the 3rd, 7th, 10th, 14th, and 21st day after injury, the wound granulation tissue of rats grew well in temperature-sensitive hydrogel group and gel group, with no obvious infection, and two rats in blank control group died of wound infection on the 3rd and 5th day after injury. On the 7th, 10th, 14th, and 21st day after injury, the wound healing rates of rats in temperature-sensitive hydrogel group and gel group were significantly higher than that in blank control group (P<0.01). On the 10th day after injury, the wound healing rate of rats in temperature-sensitive hydrogel group was significantly higher than that in gel group (P<0.05). A large number of neutrophils and lymphocytes infiltrated into the wounds of rats in the three groups on the 3rd day after injury. The infiltration of inflammatory cells was gradually reduced and the wound healed gradually in rats of temperature-sensitive hydrogel group and gel group from the 7th to 21st day after injury, and the epidermis and dermis could be seen, without hair follicles and other skin appendages. The wounds of rats in blank control group did not heal completely on 21st day after injury. From the 3rd to 10th day after injury, the newly formed collagen fibers increased gradually in the wounds of rats in the three groups. On the 14th and 21st day after injury, the collagen fibers in the wounds of rats in temperature-sensitive hydrogel group and gel group were denser and more orderly than those in blank control group. On the 10th, 14th, and 21st day after injury, the collagen volume fraction of wounds of rats in temperature-sensitive hydrogel group and gel group was significantly higher than that in blank control group (P<0.01). On the 14th day after injury, the collagen volume fraction of wounds of rats in temperature-sensitive hydrogel group was significantly higher than that in gel group (P<0.01). On the 3rd, 7th, and 10th day after injury, the expressions of IL-6 in wounds of rats in temperature-sensitive hydrogel group were significantly higher than those in gel group and blank control group (P<0.01), and the expressions of IL-6 in wounds of rats in gel group were significantly lower than those in blank control group (P<0.01). On the 3rd, 7th, and 10th day after injury, the expressions of TGF-β1 in wounds of rats in temperature-sensitive hydrogel group were significantly higher than those in gel group and blank control group (P<0.01). The expressions of TGF-β1 in wounds of rats in gel group were significantly lower than those in blank control group on the 3rd and 7th day after injury (P<0.01), and the expression of TGF-β1 in wounds of rats in gel group was significantly higher than that in blank control group on the 10th day after injury (P<0.01). On the 14th day after injury, the expression of TGF-β1 in wounds of rats in gel group was significantly higher than that in temperature-sensitive hydrogel group and blank control group (P<0.01). On the 21st day after injury, the expression of TGF-β1 in wounds of rats in temperature-sensitive hydrogel group was significantly lower than that in gel group and blank control group (P<0.01), and the expression of TGF-β1 in wounds of rats in gel group was significantly lower than that in blank control group (P<0.01). On the 7th day after injury, the expression of MMP-1 in wounds of rats in gel group was significantly higher than that in temperature-sensitive hydrogel group and blank control group (P<0.01). On the 10th, 14th, and 21st day after injury, the expressions of MMP-1 in wounds of rats in temperature-sensitive hydrogel group were significantly higher than those in gel group and blank control group (P<0.01). On the 10th day after injury, the expression of MMP-1 in wounds of rats in gel group was significantly lower than that in blank control group (P<0.01). On the 14th and 21st day after injury, the expressions of MMP-1 in wounds of rats in gel group were significantly higher than those in blank control group (P<0.01). Conclusions: Temperature-sensitive hydroxybutyl chitosan hydrogel can promote the healing of full-thickness skin defect wounds in rats by increasing the expressions of IL-6, TGF-β1, and MMP-1, regulating the wound healing environment, inhibiting inflammatory reaction, improving the strength of tissue repair, and promoting collagen synthesis or decomposition.

Abstract
Diphlorethohydroxycarmalol (DPHC), a type of phlorotannin isolated from the marine alga Ishige okamurae, reportedly alleviates impaired glucose tolerance. However, the molecular mechanisms of DPHC regulatory activity and by which it exerts potential beneficial effects on glucose transport into skeletal myotubes to control glucose homeostasis remain largely unexplored. The aim of this study was to evaluate the effect of DPHC on cytosolic Ca2+ levels and its correlation with blood glucose transport in skeletal myotubes in vitro and in vivo. Cytosolic Ca2+ levels upon DPHC treatment were evaluated in skeletal myotubes and zebrafish larvae by Ca2+ imaging using Fluo-4. We investigated the effect of DPHC on the blood glucose level and glucose transport pathway in a hyperglycemic zebrafish. DPHC was shown to control blood glucose levels by accelerating glucose transport; this effect was associated with elevated cytosolic Ca2+ levels in skeletal myotubes. Moreover, the increased cytosolic Ca2+ level caused by DPHC can facilitate the Glut4/AMPK pathways of the skeletal muscle in activating glucose metabolism, thereby regulating muscle contraction through the regulation of expression of troponin I/C, CaMKII, and ATP. Our findings provide insights into the mechanism of DPHC activity in skeletal myotubes, suggesting that increased cytosolic Ca2+ levels caused by DPHC can promote glucose transport into skeletal myotubes to modulate blood glucose levels, thus indicating the potential use of DPHC in the prevention of diabetes.

Abstract
Particulate matter (PM) contributes to air pollution and primarily originates from unregulated industrial emissions and seasonal natural dust emissions. Fucoxanthin (Fx) is a marine natural pigment from brown macroalgae that has been shown to have various beneficial effects on health. However, the effects of Fx on PM-induced toxicities in cells and animals have not been assessed. In this study, we investigated the anti-inflammatory potential of the Fx-rich fraction (FxRF) of Sargassum fusiformis against PM-mediated inflammatory responses. The FxRF composition was analyzed by rapid-resolution liquid chromatography mass spectrometry. Fx and other main pigments were identified. FxRF attenuated the production of inflammatory components, including prostaglandin E2 (PGE2), cyclooxygenase-2, interleukin (IL)-1β, and IL-6 from PM-exposed HaCaT keratinocytes. PM exposure also reduced the levels of nitric oxide (NO), tumor necrosis factor-α, inducible nitric oxide synthase (iNOS), and PGE2 in PM-exposed RAW264.7 macrophages. Additionally, the culture medium from PM-exposed HaCaT cells induced upregulation of NO, iNOS, PGE2, and pro-inflammatory cytokines in RAW264.7 macrophages. FxRF also significantly decreased the expression levels of factors involved in inflammatory responses, such as NO, reactive oxygen species, and cell death, in PM-exposed zebrafish embryos. These results demonstrated the potential protective effects of FxRF against PM-induced inflammation both in vitro and in a zebrafish model.

Abstract
Objective: To compare the difference and agreement of corneal refractive power and astigmatism measured by the new swept-source anterior segment optical coherence tomography (SS-AS-OCT) device (CASIA2) and Scheimpflug imaging device (Pentacam) in age-related cataract patients. Methods: In this cross-sectional study, 112 eyes of 112 patients with age-related cataract were examined before phacoemulsification in the Tianjin Medical University Eye Hospital from April to May 2020. The steep keratometry (Ks), flat keratometry (Kf), mean keratometry (Km), degree and axis of astigmatism of the corneal anterior and posterior surfaces and the total cornea were recorded. The difference in astigmatism was analyzed by the arithmetic method and the vector method. The difference of data was evaluated using Paired t test or Wilcoxon test. The agreement of data was evaluated using Bland-Altman plots. Results: The patients were 44 males and 68 females with an average age of (67±10) years. There were no statistically differences in the Ks and Km values of the corneal anterior surface between the Pentacam and the CASIA2 (both P>0.05). There was significant difference in the Kf values of the corneal anterior surface between the Pentacam and the CASIA2 [(44.24±1.73) D vs. (44.14±1.64) D; t=2.278; P<0.05]. The Ks, Kf, and Km values of the posterior surface of the cornea measured by the Pentacam and the CASIA2 were (-6.60±0.29) D vs. (-6.45±0.28) D, (-6.34±0.27) D vs. (-6.17±0.25) D, and (-6.47±0.26) D vs. (-6.31±0.25) D, respectively. The Ks, Kf, and Km values of the total cornea measured by the two instruments were (45.08±1.84) D vs. (43.94±1.64) D, (44.18±1.85) D vs. (43.02±1.64) D, and (44.63±1.82) D vs. (43.48±1.60) D, respectively. There were significant differences in the Ks, Kf, and Km values of the posterior surface of the cornea and the total cornea (t=-14.440, -13.522, -17.186, 21.016, 21.819, 22.981; all P<0.01). The degree and axis of astigmatism of the corneal anterior and posterior surfaces and the total cornea showed no statistically significant difference (all P>0.05). Vector operation results showed that the astigmatism difference vector (DV) of the Pentacam and the CASIA2 on the anterior surface of the cornea was 0.06 D@57°±0.64 D,>0.50 D in 47 eyes (41.96%). The astigmatism DV on the posterior surface of the cornea was 0.07 D@174°±0.21 D, >0.50 D in 2 eyes (1.79%). The astigmatism DV on the total cornea was 0.13 D@3°±0.69 D,>0.50 D in 59 eyes (52.68%). The results of the two devices were positively correlated (r values of the Ks, Kf, Km, and astigmatism degree on the anterior surface of the cornea were 0.970, 0.968, 0.976, and 0.697, respectively, on the posterior surface of the cornea were 0.918, 0.875, 0.925, and 0.517, respectively, and on the total cornea were 0.951, 0.955, 0.959, and 0.622, respectively; all P<0.01). Bland-Altman analysis showed that the Ks, Kf, Km, and astigmatism degree of the corneal anterior and posterior surfaces measured by the two devices were consistent, with 2.68% to 8.04% of the measured values outside 95% limits of agreement (95%LoA). The 95%LoA of the total corneal Ks, Kf, and Km between the two devices was 0.01 to 2.28 D, 0.06 to 2.27 D, and 0.10 to 2.20 D, respectively, with a wide 95%LoA range and poor consistency. Conclusions: The corneal refractive power and astigmatism measured by the CASIA2 and the Pentacam shows little difference on the anterior surface of the cornea, with good agreement. However, the refractive power results of the posterior surface of the cornea and the total cornea show great difference, suggesting that these two instruments cannot be used interchangeably in clinical practice.

Abstract
Early prognostication of neurological outcome in comatose patients after cardiac arrest (CA) is vital for clinicians when assessing the survival time of sufferers and formulating appropriate treatment strategies to avoid the withdrawal of life‐sustaining treatment (WLST) from patients. However, there is still a lack of sensitive and specific serum biomarkers for early and accurate identification of these patients. Using an isobaric tag for relative and absolute quantitation (iTRAQ)‐based proteomic approach, we discovered 55 differentially expressed proteins, with 39 up‐regulated secreted serum proteins and 16 down‐regulated secreted serum proteins between three comatose CA survivors with good versus poor neurological recovery. Then, four proteins were selected and were validated via an enzyme‐linked immunosorbent assay (ELISA) approach in a larger‐scale sample containing 32 good neurological outcome patients and 46 poor neurological outcome patients, and it was confirmed that serum angiotensinogen (AGT) and alpha‐1‐antitrypsin (SERPINA1) were associated with neurological function and prognosis in CA survivors. A prognostic risk score was developed and calculated using a linear and logistic regression model based on a combination of AGT, SERPINA1 and neuron‐specific enolase (NSE) with an area under the curve of 0.865 (P < .001), and the prognostic risk score was positively correlated with the CPC value (R = 0.708, P < .001). We propose that the results of the risk score assessment not only reveal changes in biomarkers during neurological recovery but also assist in enhancing current therapeutic strategies for comatose CA survivors.

Abstract
We had observed in our previous study that the active fucoidan (JHCF4), isolated from the crude fucoidan in acid-processed Hizikia fusiforme, possessed an anticancer effect. In this study, the antioxidant effect of JHCF4 was evaluated. Among the fractions, JHCF4 showed the highest scavenging activity against 2, 2-diphenyl-1-picrylhydrazyl (DPPH), alkyl, and hydroxyl radicals, as well as protective effect against reactive oxygen species (ROS) in 2, 2'-azobis (2-amidinopropane) dihydrochloride (AAPH)-treated Vero cells. Furthermore, JHCF4 showed a protective activity against AAPH-induced apoptosis, as observed by nuclear staining with Hoechst 33342. Our results showed that JHCF4 can up-regulate Bcl-xL, down-regulate Bax and cleave caspase-3 with increased concentrations in AAPH-induced Vero cells. JHCF4 induced anti-apoptosis via a mitochondria-mediated pathway. Additionally, JHCF4 was selected for further in vivo screening in a zebrafish model, which markedly decreased ROS generation and lipid peroxidation. Thus, JHCF4 showed a potential protective activity against AAPH-induced ROS both in vitro and in the zebrafish model.

Abstract
BACKGROUND The high cost and insufficient supply of human papillomavirus (HPV) vaccines have slowed the pace of controlling cervical cancer. A phase III clinical trial was conducted to evaluate the efficacy, safety, and immunogenicity of a novel Escherichia coli-produced bivalent HPV-16/18 vaccine. METHODS A multicenter, randomized, double-blind trial started on November 22, 2012 in China. In total, 7372 eligible women aged 18-45 years were age-stratified and randomly assigned to receive three doses of the test or control (hepatitis E) vaccine at months 0, 1, and 6. Co-primary endpoints included high-grade genital lesions and persistent infection (over 6 months) associated with HPV-16/18. The primary analysis was performed on a per-protocol susceptible population of individuals who were negative for relevant HPV type-specific neutralizing antibodies (at day 0) and DNA (at day 0 through month 7) and who received three doses of the vaccine. This report presents data from a prespecified interim analysis used for regulatory submission. RESULTS In the per-protocol cohort, the efficacies against high-grade genital lesions and persistent infection were 100.0% (95% confidence interval = 55.6% to 100.0%, 0 of 3306 in the vaccine group vs 10 of 3296 in the control group) and 97.8% (95% confidence interval = 87.1% to 99.9%, 1 of 3240 vs 45 of 3246), respectively. The side effects were mild. No vaccine-related serious adverse events were noted. Robust antibody responses for both types were induced and persisted for at least 42 months. CONCLUSIONS The E coli-produced HPV-16/18 vaccine is well tolerated and highly efficacious against HPV-16/18-associated high-grade genital lesions and persistent infection in women.

Abstract
In this study, the saponin-rich fractions of five individual (two Red and three Black) sea cucumbers (Apostichopus japonicus) in South Korea were investigated for their antiproliferative effect against HL-60, B16F10, MCF-7, and Hep3B tumor cell lines. The red sea cucumber saponin-rich fraction (SSC) from Jeju Island (JRe) decreased the growth of HL-60 with an IC50 value of 23.55 ± 3.40 μg/mL, which represented the strongest anticancer activity among the extracts. Further, SSC downregulated B-cell lymphoma extra-large (Bcl-xL), while upregulating, to different degrees, Bcl-2-associated X protein (Bax), caspase-9, caspase-3, PARP cleavage, and apoptotic bodies in cancer cells. Evidence for SSC inducing apoptosis via the mitochondria-mediated pathway was found. The contents of SSCs were determined using ultra high-performance liquid chromatography coupled with a quadrupole orbitrap mass spectrometry to comparatively evaluate the regional influence. In West Sea, the total SSC content of A. japonicus was 15.5 mg/g, representing the highest content, while A. japonicus in the South Sea yielded the lowest content at 8 mg/g. The major saponin constituent in SSC was identified as Holotoxin A1, which may the anti-tumor compound in A. japonicus.

Abstract
BACKGROUND Gastric lavage (GL) is one of the most critical early therapies for acute paraquat (PQ) poisoning; however, details of the treatment protocol remain to be established. METHODS A rapid quantitative method involving sodium dithionite testing was developed. It was validated for the determination of the PQ concentrations in gastric juice and eluate samples from a swine acute PQ poisoning model with early or delay GL, or without. The vital signs, laboratory testing, and PQ plasma concentrations were collected for therapeutic effect evaluation. RESULTS The reaction conditions of the test were optimized for two types of samples. Early GL at one hour (H1) could improve the signs and symptoms after acute PQ poisoning at 24 hours (H24). In contrast, GL at 6 hours (H6) could only partially relieve the vital signs. The H1 GL group effectively reduced the peak of the plasma PQ concentration. In addition, the PQ concentrations in the plasma and the gastric juice were significantly decreased in both the GL groups as compared to the untreated group at H24. Moreover, there was no significant difference in the washing efficiencies calculated from the total eluates between the two GL groups. However, the washing efficiency of the first 10 L eluate is superior to that of the additional 10 L eluate. CONCLUSION GL only at early stage may it benefit PQ poisoning in an animal model. The currently used 20 L GL volume may need to be reduced in view of the low washing efficiency in the later 10 L eluate. The rapid quantitative method can be used for gastric juice sample and has a certain value for clinical GL practices.

Abstract
The aim of this study was to investigate the antiproliferative effects of fucoidan from three regional hijiki (Hizikia fusiforme) samples (Zhejiang-China, Jeju-Korea [JH], and Wando-Korea) in East Asia. Hijiki was processed using 1% citric acid to decrease heavy metal content. The JH sample was separated using diethylaminoethyl-cellulose-ion exchange chromatography to obtain four active fractions (JHCF1-JHCF4) and their monosaccharide composition was detected using high-performance liquid chromatography. The structure of the crude polysaccharides and four fucoidan fractions was analyzed using Fourier-transform infrared spectroscopy. JHCF4 showed the highest fucose and sulfate content and decreased Hep3B cell growth in 48 h with a half-maximal inhibitory concentration of 33.53 ± 2.50 μg/ml, which represented the strongest anticancer activity. Further, nuclear staining with Hoechst 33342 and acridine orange-ethidium bromide staining demonstrated that the anticancer activity of JHCF4 was mediated by apoptosis. Moreover, JHCF4 down-regulated B-cell lymphoma extra-large, while up-regulating Bcl-2-associated X protein, caspase-3, and apoptotic bodies to different degrees in Hep3B cells. JHCF4 induced apoptosis via the generation of reactive oxygen species along with the concurrent loss of mitochondrial membrane potential, indicating the potential role of the mitochondria-mediated pathway. Therefore, these results indicate that JHCF4 exhibited antiproliferative effects on the investigated cancer cell lines.

Abstract
OBJECTIVES Our goal was to examine whether interleukin-1 beta (IL-1β) originates locally and its possible relationship with matrix metalloproteinases (MMPs), apoptosis, elastin fibres and biomechanics in aortic dissecting aneurysms (DAs). METHODS Aortic DAs were induced in 24 rats with β-aminopropionitrile (BAPN); another 12 rats without BAPN were designated as controls. Then IL-1β levels were measured both in the circulation and in local aortic specimens. The expression of MMP-2 and MMP-9 and Victoria blue and TUNEL staining were also detected. Biomechanical parameters such as the elasticity modulus were used to detect the biomechanical changes in the aortic wall. The correlation of IL-1β, MMP-2, MMP-9, apoptosis and biomechanical properties was analysed. RESULTS Seventeen rats (17/24, 71%) in the BAPN-treated group died of DA rupture. IL-1β levels were dramatically increased in the DA specimens but not in the circulation. Victoria blue staining confirmed the formation of the DA and the reduction of elastin content after induction by BAPN. The extent of apoptosis in the aortic media was dramatically higher in rats with BAPN-induced DA than that in the control group and that in rats treated with BAPN but without DA. MMP-2 and MMP-9 levels were significantly increased in BAPN-treated rats compared to the controls, but no statistical significance was found between rats with and without DA. There were significant differences in biomechanical parameters, such as the elasticity modulus. Among the 3 groups, IL-1β was positively correlated with MMP-2 and MMP-9 levels and with the elasticity modulus but not with apoptosis. CONCLUSIONS Local IL-1β might participate in the formation of aortic DA through the upregulation of MMP-2 and MMP-9 and the breakage of elastin fibres, which finally weakens the biomechanical properties of the aortic wall.

Abstract
Objective: To compare the surgical induced astigmatism(SIA) of the total, anterior and posterior cornea between eyes with 2.2-mm and 3.0-mm clear corneal incisions in phacoemulsification. Methods: A prospective double-blind randomized controlled study was conducted on 131 patients (131 eyes) with age-related cataract from October 2017 to June 2018. They were randomized according to the random number table. Sixty-nine patients received phacoemulsification through a 2.2-mm clear corneal incision at 140 degrees; 62 patients were recruited in the control group with a 3.0-mm clear corneal incision at the same position. Lens density was graded and compared between the groups preoperatively. Total corneal refractive power (TCRP), simulated keratometry (SimK) and posterior corneal astigmatism (PCA) (Apex, 4-mm zone) were recorded through the Pentacam preoperatively and at 1 week, 1 month and 3 months postoperatively. Corneal astigmatism was decomposed to vertical/horizontal (X) and oblique changes (Y) using the power vector analysis. Independent sample t test and matched t test were used for statistical analysis. Results: A total of 123 patients (123 eyes) completed 3 months of follow-up including 65 in the 2.2-mm group and 58 in the control group. The age of the two groups was (69±9) and (71±10) years old, and the lens density was (2.08±0.47) and (2.12±0.46) grades, respectively. Both the age and the lens density of the two groups were not statistically significant (both P>0.05). Preoperative TCRP, SimK and PCA were not statistically significant (all P>0.05). SIA was calculated using the vector analysis. Centroid SIA conducted from TCRP, SimK and PCA in the 2.2-mm group was -0.11 D@146°, -0.11 D@151° and -0.03 D@67°, respectively, at 3 months postoperatively. In the 3.0-mm group, it was -0.25 D@158°, -0.24 D@147° and -0.04 D@47°, respectively. Statistical significance was found between the two groups in the Y polar value of SIA of the anterior surface [(-0.10±0.30) vs.(-0.22±0.37) D, t=-2.133, P=0.035] and the SIA of the posterior surface [(0.24±0.16) vs. (0.19±0.12) D, t=2.009, P=0.047] at 3 months postoperatively. In the comparison of the SIA of TCRP and anterior surface, statistical significance was found in the absolute value of SIA at all the intervals in the 2.2-mm group [(0.87±0.80) vs. (0.58±0.48) D, (0.58±0.48) vs. (0.50±0.28)D, (0.57±0.37) vs. (0.47±0.28) D, t=5.102, 4.155, 3.877, all P<0.01] and at 1 week and 1 month in the 3.0-mm group [(0.82±0.57) vs. (0.58±0.41) D, (0.59±0.36) vs. (0.50±0.28) D, t=5.034, 3.919, both P<0.01]. X components of SIA(TCRP) and SIA(simk) were significantly different at 3 month postoperatively in 3.0-mm group (P<0.05). Y components of SIA(TCRP) and SIA(SimK) were significantly different at 1 week postoperatively in the 2.2-mm group[(-0.48±0.85) vs.(-0.24±0.42) D, P<0.01] and 3.0-mm group [(-0.58±0.66) vs. (-0.37±0.42) D, P<0.01]. Conclusions: Compared with the 3.0-mm incision, the 2.2-mm coaxial micro-incision cataract surgery has a lower and more stable SIA. The effect of a clear corneal incision in cataract surgery on the total cornea is more obvious than that on the anterior surface of the cornea. The difference is significant in the early stage and gradually decrease with time. (Chin J Ophthalmol, 2019, 55: 495-501).

Abstract
Objective: To explore the relationship between coronary tortuosity and coronary microvascular disease (CMVD). Methods: Patients with typical angina symptoms and without serious coronary artery stenosis by coronary angiography were enrolled from June 2014 to December 2016, and CMVD was diagnosed by single photon emission tomography (SPECT). According to the SPECT results, patients were divided to the CMVD group and non-CMVD group. The baseline clinical characteristics, results of coronary angiography were compared between the two groups. The logistic analysis was used to analyze the relationship between coronary tortuosity and CMVD. Result: A total of 117 cases were enrolled, with 69 cases in the CMVD group and 48 cases in the non-CMVD group. No differences were found in gender distribution, age, hypertension, lipid abnormality, hyperuricemia and uses of statins between the two groups (all P>0.05). Incidence of diabetes (78.26%(54/69) vs. 35.42% (17/48) , P<0.05), hs-CRP ((4.29±2.15)mmol/L vs. (2.63±1.20)mmol/L, P<0.001), LDL-C ((2.98±0.96)mmol/L vs. (2.52±0.83)mmol/L, P=0.008) and homocysteine ((13.7±5.61)mmol/L vs. (11.5±4.38)mmol/L, P=0.025) levels were higher in the CMVD group than in the non-CMVD group. The data derived from echocardiographic examination were similar between the two groups. The Corrected TIMI frame counts were higher in the CMVD group than in non-CMVD group (LAD: 31.56±4.92 vs. 27.31±3.75, LCX: 29.47±4.18 vs. 26.62±3.19, RCA: 29.09±5.05 vs. 26.24±3.28, all P<0.001). The incidences of coronary atherosclerosis (76.81% (53/69) vs. 27.08% (13/48) , P<0.001) and coronary tortuosity ( (60.87% (42/69) vs. 33.33% (16/48) , P=0.035) were also higher in the CMVD group than in non-CMVD group. Logistic analysis found that coronary tortuosity (OR=6.111, 95%CI 2.707-13.794, P<0.001), diabetes (OR=6.565, 95%CI 2.883-14.948, P<0.001) and coronary atherosclerosis (OR=8.918, 95%CI 3.822-20.808, P<0.001) were independent risk factors of CMVD. Conclusion: Coronary tortuosity, diabetes and coronary atherosclerosis are related to CMVD in this patient cohort.

Abstract
Objective:To study the auditory language ability of children with artificial cochlea after entering normal schools as well as the school life conditions and to evaluate the long-term comprehensive benefits of surgery on children along with their families. Method:The questionnaire was designed referring to the categories of auditory performance (CAP), the speech intelligibility rating (SIR), and family burden scale of diseases (FBS), with the questions involving four aspects of the general conditions, the auditory language ability, the school life conditions and the family conditions. Altogether 50 families were participated. Children who had applied artificial cochlea for at least two years and studied in normal schools were selected as the studying objects. The follow-up questionnaire was conducted on the parents. The differences were compared in the auditory language ability and the school life conditions, grouped by gender, age at surgery, parents' educational level, residence, service time of artificial cochlea and parent-child time in general. Meanwhile, the differences of 15 family conditions were compared before and after surgery. Result:The variable factors were of no obvious statistical significance in the comparison among groups of the auditory language ability (P>0.05); In the comparison of the school life conditions, there were significant differences in the number of making friends when grouped by parent-child time (P<0.05), there wes no statistical significance in the comparison among groups of the remaining various factors (P>0.05); In the comparison of family conditions before and after surgery, the rest of the indexes were of significant differences (P<0.05), there was no significant differences in the economic burden and social time of parents (P>0.05). Family conditions improved evidently after surgery. Conclusiont:Under the circumstances of different variable factors, after 2 years of rehabilitation, children are able to acquire better auditory language ability, and adjust themselves to the school life, finishing their studies, still there is a deficiency in the aspect of organizational competence in comparison to age-matched children. In addition, with children's recovery and attending schools, parents' mental stress is significantly reduced, family life returns to normal, and family atmosphere becomes harmonious. Not only can the artificial cochlea help rid children of disability, but also it can be of obvious benefits to their families.

Abstract
Objective: To systematically compare the differences in the detection rate of prostate cancer with fusion targeting biopsy and systemic biopsy. Methods: A computer-based search of PubMed, Medline, China Biomedical Literature Database and Wanfang database (from the beginning of establishment of library to October 2016) on the detection rate of prostate cancer by fusion targeting biopsy and systemic biopsy was performed manually.The inclusion and exclusion criteria were formulated by 2 reviewers, and the data were extracted and evaluated respectively. RevMan5.3 software was used to analyze the detection rate of prostate cancer by two biopsy methods. Results: A total of 15 related clinical studies were included, 5 337 cases were enrolled in the study, including 2 667 cases of targeted fusion biopsy and 2 670 cases of routine systemic biopsy. The results showed that the overall detection rate of prostate cancer in targeting fusion biopsy was significantly higher than that of conventional systemic biopsy (OR=1.16, 95% CI 1.04-1.30, P=0.007). The detection rates of prostate cancer with different risk grades by two biopsy methods were conducted. We found that targeted fusion biopsy had a significant advantage compared with conventional system biopsy (OR=1.37, 95% CI 1.19-1.58, P<0.05) in middle and high risk prostate cancer with Gleason ≥ 7 points. In low-risk prostate cancer patients with Gleason score <7, the detection rate of prostate cancer by targeted fusion biopsy was lower (OR=0.76, 95% CI 0.65-0.89, P<0.05) than that of conventional systemic biopsy. Conclusions: Targeted fusion biopsy was significantly better than systemic biopsy in the overall detection rate of prostate cancer and the detection rate of the middle and high risk prostate cancer with Gleason ≥7 points. However, systemic biopsy performed better in patients with Gleason<7 points of low-risk prostate cancer.

Abstract
BACKGROUND/PURPOSE Autofluorescence has become an important factor associated with diagnosis and treatment of many diseases. METHODS Full thickness skin grafts and scar biopsies were obtained from five volunteers. The normal skin or scar tissue paraffin-wax sections were stained with HE and the autofluorescence of collagen fibres was viewed under fluorescence microscopy. RESULTS In normal skin, the autofluorescence was showed in dermis, specifically in collagen fibres. There was very weak autofluorescence in epidermis. The spectrum was excited at 488 nm and the peak value of autofluorescence was significantly different between reticular layer (169.24±9.18) and papillar layer of dermis (103.91±15.23). In scar tissue, the autofluorescence was showed in collagen fibres and the peak value was 176.71±20.69. The structure of collagen fibres in normal skin or scar tissue was different in loose degree, thickness, boundle size, and morphology by their autofluorescence. CONCLUSION The different peak value of autofluorescence between scar and normal skin may due to the different density of collagen fibtes in them. This study may provide us a simple and effective assessment indicator and method for diagnosis and treatment of scar.

Abstract
The objective of this study was to assess whether vitamin D (VD) treatment alters the overall all-cause and cardiovascular mortalities in a chronic kidney disease (CKD) population. We systematically searched PubMed, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials without language restriction, until the publication date of 22 February 2016. All related literatures that compared VD treatment with non-VD treatment and reported the mortality of patients with CKD (including those undergoing dialysis) were identified. Pooled risk ratios (RR) and 95% confidence intervals (CI) were calculated by using the random- and fixed-effects models. Randomised controlled trials (RCTs) that used the intention-to-treat principle and observational studies (OSs) were analysed separately. For this study, 38 studies involving 223 429 patients (17 RCTs, n=1819 and 21 OSs, n=221610) were included. In the OSs, VD treatment was significantly associated with reductions in both all-cause and cardiovascular mortalities; however, such significant association was not found in the RCTs. The existing RCTs do not provide sufficient or precise evidence that VD supplementation affects the mortality of patients with CKD, although subsets of patients that could potentially benefit from VD treatment can be identified by using the existing data from the RCTs. Nevertheless, large-size RCTs are needed in the future to assess any potential differences in survival prospectively.

Abstract
BACKGROUND Preterm neonates undergo many painful procedures as part of their standard care in the neonatal intensive care unit. However, pain treatment is inadequate in many of these routine procedures. In the present study, we investigated the impact and mechanism of combined music and touch intervention (CMT) on the pain response in premature infants. METHODS Sixty-two preterm neonates (gestational age of <37 weeks) were randomly assigned to either the experimental or control group. Infants in the experimental group underwent painful procedures with CMT, and those in the control group underwent painful procedures without CMT. Blood samples were collected from all infants at the beginning of hospitalization and 2 weeks later to assess the cortisol and β-endorphin concentrations. Differences in the levels of cortisol and β-endorphin between two groups were examined using analysis of covariance (ANCOVA). RESULTS In total, 3707 painful procedures were performed on 62 neonates during their hospitalization. The average number of painful procedures in the control group (n = 35.5) was higher than that in the experimental group (n = 29.0) during hospitalization, although no significant difference was reached (P > 0.05). After 2 weeks, the Premature Infant Pain Profile scores were significantly higher in the control group than experimental group (13.000 ± 0.461 vs 10.500 ± 0.850, respectively; P < 0.05). The cortisol concentration was not significantly different between the control and experimental groups either at the beginning of hospitalization (131.000 ± 18.190 vs 237.200 ± 43.860, respectively; P > 0.05) or 2 weeks later (162.400 ± 23.580 vs 184.600 ± 21.170, respectively; P > 0.05). However, the serum β-endorphin concentration was higher in the experimental group than in the control group both at the beginning of hospitalization (1.640 ± 0.390 vs 1.179 ± 0.090, respectively; P < 0.05) and 2 weeks later (2.290 ± 0.740 vs 1.390 ± 0.410, respectively; P < 0.05). CONCLUSIONS CMT might decrease the pain response of preterm neonates by significantly improving the β-endorphin concentration, but not the blood cortisol concentration.

Abstract
We investigated the proliferation and differentiation potential of human osteoblasts from a type 2 diabetic patient in vitro. Human osteoblasts were obtained from a healthy subject and a type 2 diabetic patient and were cultured in vitro using the tissue explant adherent method. Differences in cell morphology were observed under a phase contrast microscope. The osteogenic differentiation capacity was evaluated by alizarin red staining, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, alkaline phosphatase (ALP) staining, and detection of bone Gla-protein (BGP) and Col-1. Expression of Runx-2 and Col-1 was detected using RT-PCR and western blot. Our data indicated that alveolar bone osteoblasts from the type 2 diabetic patient exhibited poorer growth, smaller calcium nodule formation, slower proliferation, and lower ALP, BGP, and Col-1 concentrations in the cell culture supernatant, as compared to control cells (P < 0.05). Combined, our study indicated that alveolar bone osteoblasts from a type 2 diabetic patient exhibited slower proliferation and decreased differentiation, as compared to healthy control, when cultured in vitro.

Abstract
AIMS The purpose of this study is to compare the antiviral efficacy of entecavir (ETV) and adefovir dipivoxil (ADV) at various time points during the treatment. METHODS A randomized, controlled, open-label study was designed to analyze the kinetics of HBeAg seroconversion, HBV DNA level, and liver and renal functions in 72 ETV-treated chronic hepatitis B (CHB) patients and 66 ADV-treated CHB patients. The data was collected every 12 weeks up to 96 weeks after drug administration. RESULTS The negative rate of HBeAg seroconversion was significantly increased at 24 weeks in ETV-treated patients, whereas in ADV-treated patients, these changes were not significant. The serum HBV DNA levels were significantly decreased from 24 weeks in both ETV- and ADV-treated patients. Other than ETV showing significantly decreased levels of HBV DNA at 24 weeks when compared with ADV, there was no difference in virological response between two treatments at any other time points. The serum alanine aminotransferase (ALT) and total bilirubin (TBIL) levels were significantly decreased 12 weeks after either ETV- or ADV-treated patients without differences between two treatments. The urea nitrogen levels were in normal range and there was no difference between two groups. CONCLUSIONS Our study suggested that both ETV and ADV could be used as monotherapy for nucleotide-naive patients, but ETV has displayed potential efficacy in HBeAg seroconversion.

Abstract
AIM To investigate the prevalence of obesity and associated risk factors in the Northeastern Chinese city of Dehui. METHODS A cross-sectional study involving random sampling methods generated 3598 completed questionnaires by permanent residents of Dehui. Binary multivariate logistic regression analysis was used to identify factors that were significantly associated with obesity. RESULTS Based on the 2000 WHO diagnostic criterion regarding populations in the Asia-Pacific region, the prevalence of obesity was 37.71% (34.77% of females; 41.11% of males). Elevated body mass index (BMI) was significantly associated with cardiovascular disease (CVD)-associated conditions (P<0.05), and increased prevalence of abnormally high transaminase levels (P<0.05). Binary logistic regression analysis demonstrated the following variables were associated with obesity: increased age (odds ratio [OR]: 1.01, 95% confidence interval [CI]: 1.0-1.02), high total cholesterol (TC) (OR: 1.26, 95% CI: 1.03-1.54), high triglycerides (TG) (OR: 1.38, 95% CI: 1.16-1.64), hypertension (OR: 1.62, 95% CI: 1.39-1.90), fatty liver (OR: 2.91, 95% CI: 2.41-3.49), living in an urban setting (OR: 2.84, 95% CI: 2.39-3.38), and advanced education (OR: 1.22, 95% CI: 1.06-1.40). CONCLUSIONS Obesity is prevalent among the adult population in Northeastern China and is significantly associated with CVD risk factors such as hypertension, dyslipidemia, as well as transaminase abnormalities.

Abstract
General characteristics of waxes, adhesives and lubricants as well as the recent fundamental investigations on their physical and mechanical behaviour are introduced. The current R&D status for new type/generation of waxes, adhesives and lubricants from natural products is reviewed, with an emphasis on their tribological applications. In particular, some crucial issues and challenges relating to technological improvement and materials development are discussed. Based on the current predicted shortage of energy resources and environmental concerns, prospective research on the development of green waxes, adhesives and lubricants is suggested.

Abstract
This epidemiological study was conducted to investigate the prevalence of metabolic syndrome and associated risk factors in Chinese subjects from Dehui in northeastern China. Using a random sampling method, a questionnaire was completed by 3785 permanent residents aged 18-72 years and relevant clinical data were collected from each subject. Binary multivariate logistic regression analysis was used to identify factors that were significantly associated with metabolic syndrome. Based on the International Diabetes Federation definition, the prevalence of metabolic syndrome was 22.4%, which is higher than that of the general Chinese population. Metabolic syndrome occurred more frequently in females and the prevalence gradually increased with age. Living in an urban setting and being female, > 50 years old, overweight, having total cholesterol ≥ 5.18 mmol/l, low-density lipoprotein cholesterol ≥ 3.1 mmol/l, and a fatty liver were significant risk factors associated with metabolic syndrome.

Abstract
Systemic LPS endotoxin is associated with acute pancreatic damage. Whether damage results from direct interaction of LPS with pancreatic cells is unknown. We addressed that question by monitoring p8 expression in reponse to LPS, in vivo and in vitro, because overexpression of the p8 protein is a sensitive marker of pancreatic agression. For in vivo studies, rats were sacrificed at different times after a single intraperitoneal injection of LPS, and pancreas, liver, kidney, lung, brain, and intestine were processed for RNA preparation. In vitro, pancreatic acinar AR4-2J cells were cultivated with 0.1, 1, or 10 micrograms/ml LPS for 6, 12, or 24 h. p8 mRNA expression was monitored by Northern blotting. In vivo, it was strongly increased in the pancreas after 12 h of treatment and remained elevated after 24 h. It was also induced in kidney and liver, with a maximum at 6 and 12 h, respectively, but not in lung, brain, or intestine. In AR4-2J cells, basal p8 mRNA expression was very low and increased in a time- and dose-dependent manner after treatment with LPS. LPS-induced overexpression of p8 mRNA in vivo confirmed the adverse effect of endotoxemia on pancreas and its overexpression in vitro demonstrated a direct interaction of LPS with pancreatic cells.

Abstract
Lympho-stromal interactions in the thymus crucially de- termine the fate of developing T cells. Epithelial cells, inter- digitating reticular cells, macrophages and fibroblasts all play a role in the shaping of the T cell repertoire. Recently published evidence shows that lympho-stromal interaction acts bi-directional. Developing T cell themselves, at different stages of differentiation, control the microarchitecture of thymic microenvironments, a phenomenon designated as 'crosstalk'. This paper reviews experiments showing that developing T cells crosstalk to different thymic epithelial cells in a stepwise fashion. In this way, correctly organized thymic microenvironments guarantee normal thymopoiesis.

Abstract
OBJECTIVE To observe the effect of "Qingkailing" (QKL) on cerebral hematoma. METHODS The experimental cerebral hematoma models were produced by injecting autogenous clot in the rabbit. The influences of QKL on blood gas, brain index, contents of water, sodium, potassium, calcium, magnesium in brain tissues and changes of cerebrovascular permeability, histomorphology at the third day, seventh day, fourteenth day after cerebral hematoma were observed. RESULTS In the pathological group brain index and contents of water, sodium, calcium of brain tissue, ventilation of lung were increased progressively, cerebrovascular permeability were raised obviously, especially in the side of hematoma (right brain). After the forming of cerebral hematoma cerebral edema was reduced, brain index, contents of water, sodium, calcium in brain tissue and cerebrovascular permeability, hyperventilation were all less than pathological group and close to the control group. CONCLUSION QKL was advantageous in the treatment of encephal edema induced by experimental cerebral hematoma.

Abstract
A common approach to identify and clone biosynthetic gene from an antibiotic-producing streptomycete is to clone the resistance gene for the antibiotic of interest and then use that gene to clone DNA that is linked to it. As a first step toward cloning the genes responsible for the biosynthesis of thiostrepton (Th) in Streptomyces laurentii (Sl), the Th resistance-encoding gene (tsnR) was cloned as a 1.5-kb BamHI-PvuII fragment in Escherichia coli (Ec), and shown to confer Th resistance when introduced into S. lividans TK24. The tsnR-containing DNA fragment was used as a probe to isolate clones from cosmid libraries of DNA in the Ec cosmid vector SuperCos, and pOJ446 (an Ec/streptomycete) cosmid vector. Sequence and genetic analysis of the DNA flanking the tsnR indicates that the Sl tsnR is not closely linked to biosynthetic genes. Instead it is located within a cluster of ribosomal protein operons.

Abstract
The fatty acid patterns of oils, blood plasma and erythrocyte lipids from 28 children in the Shaanxi province of the People's Republic of China were determined by capillary gas liquid chromatography. The main source of fat in this region is rapeseed oil. The analysis of locally available rapeseed oil shows a high erucic acid content (mean 43.83%, range 33.91-50.48%). According to protocol data, about 3% of the daily nutrient energy is provided by erucic acid. Despite a low fat intake in Chinese children, the composition of the fatty acids of the fractions analyzed showed normal patterns. However, erucic acid was found in all fractions analyzed. Data on erucic acid in human tissue are scarce. Although there are no indications of erucic acid toxicity in man, it is known to cause cardiac lipidosis and necrosis in rats. The question remains open if erucic acid aggravates selenium deficiency symptoms which are known to be associated with Keshan disease, an endemic cardiomyopathy.

Abstract
Ofloxacin was used in the treatment of 20 cases of typhoid fever, 32 cases of bacillary dysentery and 50 cases of gonococcal infection. Altogether 102 cases were treated, 53 being male and 49 female. The daily dosage was 400 mg to 600 mg, divided into two times. The result showed that the clinical effective rate for typhoid fever, bacillary dysentery and gonococcal infections was 100%, 97% and 94% respectively, while the bacterial eradication rate was 100%, 100% and 94% respectively. the bacterial eradication rate was 100%, 97% and 94% respectively. The side effects were mild in degree. The authors are of the opinion that since ofloxacin can be administered orally with only two times a day, its absorption is nearly complete and the cure rate is high, it should be considered as the drug of choice in the treatment of typhoid fever, bacillary dysentery and gonorrhea, especially in the drug resistant cases. It is suggested that this drug be used more widely.

Abstract
This paper presents the establishment of a human pulmonary adenocarcinoma cell line Lu-YePa and its biological characteristics. The primary cells of Lu-YePa cell line were derived from a twenty six year old patient with poorly differentiated adenocarcinoma of the lung. After 36 days' culture, transfer was made and the cells proliferated steadily and rapidly afterwards. The doubling time was 34.6 hours. Mitotic index reached 49.5% on day 5. Chromosome number was subtriploid with the mode of 62. The large submetacentric marker chromosome was presented in 68% of cells. PAS positive granules were found in the cytoplasm. The study of concanavalin A condensation, electron microscopic observation, heterotransplantation and plating efficiency indicates that Lu-YePa cells are concordant with the human pulmonary adenocarcinoma cells in morphology and biological behavior.
